Текст копии от Vim 7.2, работающего в xterm к буферу обмена окон

If you were running vim locally, then either

"+p
"*p

would work, as mentioned by hacker. Since you're sshed into another box, these will just copy text to the clipboard of the box you're sshed into.

What you need is the putty method of copying text, which is just highlighting the text you want to copy with the mouse.

While sshed into vim though, I usually use ALT + highlight with the mouse (for block selection), as I usually have line numbers on.

Hope this helps!
